Decide whether the equation is an identity, a conditional equation, or a contradiction. Give the solution set.
-$$- 8 x - 42 + 2 ( 4 x + 23 ) = 0$$
A) Contradiction; $\varnothing$
B) Conditional; $\{ 4 \}$
C) Identity; $\{$ all real numbers $\}$
D) Conditional; $\{ 1 \}$

Question

Quizplus · Accepted Answer

The equation simplifies to $4 = 0$, which is a contradiction, meaning there are no solutions.

Decide Whether the Equation Is an Identity, a Conditional Equation −8x−42+2(4x+23)=0- 8 x - 42 + 2 ( 4 x + 23 ) = 0−8x−42+2(4x+23)=0

Decide Whether the Equation Is an Identity, a Conditional Equation $- 8 x - 42 + 2 ( 4 x + 23 ) = 0$
